Abstract

The present invention relates to a kind of efficient noise elimination elbows.Metal plate of traditional elbow by sheet metal or with sound absorption interlayer forms, and does not have noise elimination function or noise elimination function is limited, is unable to reach noise criteria, realizes health office.Present invention composition includes: the elbow (1) with efficient noise elimination function, the elbow includes a metal framework (2), the metal framework is 90 ° of elbow channels being made of metal plate, the bloop (3) of 90 ° of bendings is installed inside the metal framework, the bloop is made of frame (4) metal plate, air inlet and exhaust outlet install semicircle public attention (5) and triangle public attention (6) respectively, and the lower portion fills nonmetallic sound-absorbing material (7).The present invention is used for efficient noise elimination elbow.

Description

Efficient noise elimination elbow
Technical field:
The present invention relates to a kind of efficient noise elimination elbows.
Background technique:
Noise pollution, atmosphere pollution, water pollution and solid waste pollution are four pollutions greatly of environment, as people are to environmental protection industry (epi) Attention, the measure for controlling noise pollution more and more applied.Traditional elbow is by sheet metal or has sound absorption folder The metal plate composition of layer, does not have noise elimination function or noise elimination function is limited, is unable to reach noise criteria, realizes health office.This The form of ventilation noise reducing apparatus at present can be simplified by inventing a kind of related efficient noise elimination elbow, can only be reached by an elbow To noise reduction effect, keep noise reducing apparatus more succinct, the design side of silencer must be arranged by breaking through high noise reduction ventilation equipment at present Method, is preferably utilized the space in elbow and elbow to the noise reduction effect of high-frequency noise, higher for certain pairs of space requirements Occasion, the solution provided.
Summary of the invention:
The object of the present invention is to provide a kind of efficient noise elimination elbows.
Above-mentioned purpose is realized by following technical scheme:
A kind of efficient noise elimination elbow, the elbow including one with efficient noise elimination function, the elbow include a metal frame Frame, the metal framework are 90 ° of elbow channels being made of metal plate, are equipped with 90 ° of bendings inside the metal framework Bloop.
The efficient noise elimination elbow, it is characterized in that: the bloop is made of frame, air inlet and air draft metal plate Mouth installs semicircle public attention and triangle public attention respectively, and the lower portion fills nonmetallic sound-absorbing material.
The bloop, it is characterized in that: the nonmetallic sound-absorbing material is made of superfine glass silk flosssilk wadding.
The utility model has the advantages that
1. metal framework of the invention is made of sheet metal, there is light-weight, easy to process, protection environment, convenient for fortune The features such as defeated.
2. bloop of the invention is mounted on inside metal framework, it is separated by distribution, due to the difference of installation site, each Noise reduction chip size is different, and bloop reduces noise using sound-absorbing porous material, bloop is mounted on the inside of airflow channel, structure At resistive muffler, when sound wave enters resistive muffler, a part of sound can rub in the hole of porous material and be converted It is dissipated at thermal energy consumption, makes to weaken by the sound wave of muffler, achieve the purpose that noise elimination, be easily installed and dismantle, and air inlet Bloop public attention is reduced bloop to the resistance of wind, is conducive to the circulation of air-flow using semicircle public attention.
3. nonmetallic sound-absorbing material of the invention is superfine glass silk flosssilk wadding, the superfine glass silk floss has acoustic absorptivity Big feature is widely used in the fields such as sound insulation, silencer.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the A-A cross-sectional view of Fig. 2.
Fig. 4 is perspective view of the invention.
Specific embodiment:
Embodiment 1:
A kind of efficient noise elimination elbow, composition includes: the elbow (1) with efficient noise elimination function, and the elbow includes One metal framework (2), the metal framework are 90 ° of elbow channels being made of metal plate, peace inside the metal framework Bloop (3) equipped with 90 ° of bendings, the bloop are made of frame (4) metal plate, and air inlet is installed respectively with exhaust outlet Semicircle public attention (5) and triangle public attention (6), the lower portion fill nonmetallic sound-absorbing material (7).The present invention is for height Imitate bend muffler.
Embodiment 2:
According to efficient noise elimination elbow described in embodiment 1, the metal framework is made of sheet metal.
Embodiment 3:
According to efficient noise elimination elbow described in embodiment 1, the bloop is made of frame, air inlet and row metal plate Semicircle public attention and triangle public attention are installed in air port respectively, and the lower portion fills nonmetallic sound-absorbing material.
Embodiment 4:
According to bloop described in embodiment 1, the nonmetallic sound-absorbing material is made of superfine glass silk flosssilk wadding.

Claims (3)

1. a kind of efficient noise elimination elbow, the elbow including one with efficient noise elimination function, the elbow include a metal framework, The metal framework is 90 ° of elbow channels being made of metal plate, is equipped with disappearing for 90 ° of bendings inside the metal framework Tablet.
2. efficient noise elimination elbow according to claim 1, it is characterized in that: the bloop constitutes frame by metal plate, Air inlet and exhaust outlet install semicircle public attention and triangle public attention respectively, and the lower portion fills nonmetallic sound absorber Material.
